OPEN-END HOLLOW TILE FOR WALL STRUCTURES.

itAHML. Ji-t.

Application To (all 10/; cm. it may concern lie it l\"fi()\\ll that l, Mxrums Doorman. a citizen of the l nited States, residing in the city of St. Louis and State of Missouri. have invented certain new and useful lm proveinents in ()pen-l lnd l'lollow Tiles for \lall Structures. of which the. following is a specification.

My invention relates to improvements in hollow tile for wall structures and has for its object to provide a tile, as hereinafter more clearly set. forth, possessing advantages in point of general utility, lightness, strength and to provide a tile which will be :i'alistinct and practical improvement to over come certain important practical objections to, and detects in, the present style of tile now used in chimney. silo. tank and other wall structures.

A further objcctot the invention is to rovide a tile having means for interlocking it with cementitious cores or fillings when laid into a wall structure.

\Vith the above and other objects in view, the invention consists in certain novel features of construction, or formation, hereinafter more fully described and finally pointed out in the claim hereto appended.

Referring to the ac onipany 5 drawings forming a part of this specifica. .on wherein like characters ot'rct'erencc denote similar parts throughout the several views:

Fig. l, is a plan view of one whole tile and a portion of a second tile laid in end to end relation.

Fig. 2, is a vertical sectional view of two courses of tile, showing the cementitious core and the vertical and horizontal reinforcing rods.

Fig. 3, is a plan view of a circular wall structure formed of tile made in accordance with my invention.

My improved hollow tile is in the form of a double I-shaped body in plan view, and consists of an inner wall section 1 and an outer wall section 2.

The inner and outer wall sections are connected by means of the cross-walls 3 and t. 1

The tile is provided with a centrally disposed circular opening 5, and the two end semicircular openings 6.

The inner and-outer wall sect ans 1 and 2 are each provided with a V-shaped rib 7 extending into the circular opening 5 in opposed relation to each other.

Specification of Letters Patent.

e A a u Patented Feb. it, that? filed October 28, 1918. Serial No. 259,964.

The inner and outer wall sections 1 and 9. are each provided. at each end, with a rib 8 extending into the end sei'nicircular open-- ings 6 in opposed relation to each other and are each of a size equal to one half the size of the ribs 7 extending into the centrallv disposed circular opening U There is an open end space 5) formed between theend ribs 8 at eaii-hendol the tile to permit lateral communication of the end semicircular openings (3 when the tiles are laid, end to end. in a wall structure so as to provide a circular opening at the break joint of each pair of tile laid end for end, as clearly shown in Figures l. and 3 ol the drawings.

A t'ter a course ol tiles has been laid into a,

all structure, as shown, for instance in Figure 3. the circular openings are filled with a cen'ientitious filling it) which forms vertical cementitious cores, or colun'ins between the. inner and outer tile wall sections I and i and the crosswwalls 3 and t. These cen'ientitious cores, or columns 10 are united near the uppe end of the tile and above each crosswall 3 and -t by cementilious lilling designated '11, which is made possible by curving or concaving the top surface of the cross walls 23 and -l-, as at '12.

The curved or coneaved upper surface of the crossovalls it and l also permits the use of horiXontai reinforcing rods 13, as'clearly shownin Figures 3 and 3, which are adapted to be enil'icdded in the cemenlilious filling, as clearly idiown in Figure Vertical rcinforcing rods l -l may also be embedded in the vertical cores of cementitious filling, as clearly shown in Figures 3 and 3.

The outside face of the outer wall section 2 ol each tile is preferably provided with a suitable vertical groove 15. localed midway its ends which gives the builder the advantage of using two styles of tile in the same wall structure with a oue-quarter bond, and where reinfm'cement is specified, the onequarter bond enables me to comply with the specified distance of vertical reintorcemcnt as the distance can be located by the roove '15 on the outside of the Full tile. lVhen two styles of tile are used, the one style is in the form ol an I-shaped block or brick, which form of tile is made the sub ject matter of a separate patent a iplication tiled October 28, 1918, Serial umber 259,963. i

The many advantages of the. herein described invention will readily suggest themselves to those skilled in the art to which it ap )ertains.

I 0 not desire to be understood as limiting myself to the details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of use without departing from the spirit and scope of my invention and the terms of the following claim, hence I wish it to be understood that I reserve the right to make any such changes or modifications as may fairly fall within the scope of the appended claim when fairly construed.

What I claim is:

A building tile of the class described comprising an inner wall section and an outer 1 ioeea i.

wall section, a pair of spaced cross-Walls uniting the inner and outer wall sections, each of said crosswalls having concaved faces to form a circular central opening in the tile and a semi-circular opening at each end of the tile, a pair of opposed ribs extending into the central opening from the inner and outer wall sections said ribs each -having a beveled inner face uniting with the concaved faces of the crosswalls to strengthen the inner and outer wall sections midway their length, facial ribs arranged in opposed relation at the extremities of the inner and outer wall sections and each of said ribs having a beveled inner face terminating with the ends of the concaved faces of the cross-walls.

In witness whereof, I have hereunto signed my name to the specification.
